Etymology: Trimma: Greek, trimma, -atos = something crushed (Ref. 45335); marinae: Named for Marina, one of the many names attributed to Aphrodite in her persona as Goddess of the Sea; also after the name of author's daughter. More on author: Winterbottom.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 9 - 26 m (Ref. 55345), usually - m (Ref. ). Subtropical; 0°C -
Western Pacific: Japan, New Guinea and Palau.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 2.0 cm SL male/unsexed; (Ref. 55345); 2.0 cm SL (female)
soft rays: 8. Diagnosis: Predorsal scales and a bony interorbital about pupil diameter in width. Second dorsal spine elongated. Fifth pelvic fin ray branched dichotomously once and 55-80% of the fourth. Scales on cheek absent; one or two cycloid scales on the upper opercle; usually two rows of scales anterior to the pelvic fin base. Snout and lower half of the caudal peduncle with a slight sprinkling of melanophores. A broad, rounded, median ridge present on the snout and anterior interorbital region. Unique to the genus, a large, bilateral, open nasal pit, instead of the usual nasal sac with anterior and posterior openings (Ref. 55345); characterized further by semi-translucent pinkish, abdomen and most of head reddish pink, merging with tapered pink stripe to middle caudal fin base; midline of snout with blue-white spot; internal white stripe above vertebral column; longitudinal scale series 23-25; predorsal scales 6-8 (Ref. 90102).
Collected from a quiet, sheltered bay (Ref. 55345). Inhabits sheltered bays in 9-26 m (Ref. 90102).

Estimates based on models
Preferred temperature (Ref. 115969
): 25.2 - 29.3, mean 28.7 °C (based on 1128 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00475 - 0.02204), b=3.03 (2.85 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
